To all whom tm/ay concern.

Be it known that Louis Dees, a citi; zen of the United States, residing at 5% Vl.

` 35th Street, Chicago, in the county of Cook following is'a specification.

This invention relates to improvements in pans and method of making; the and moreespecially to a pan, saches a 'oalru ing pan, adapted to 'be mede from a. dat

.sheet or blank of metal, and having seamless rounded bottom corners tree from folds or creases.4 Such rounded corners are very .desirable in pans, such as'baking pans and the like, and have many advantages." For example, they make the pan sanitary, permit it to loe easily cleaned, and also strengthen it and make it more durable.

My invention Will be fully understood froml the followingr specification, together with the accompanying' drawings, in which is shovgn a form of device embodyingthe features of my invention. ln such drawings, Fig. l is a View oi' the blank Jfrom which the pan is made, showing the same after the lirst step of the process or method ot making the pan has been peritel-ined, Flu. 2 is a View taken as indicated by the line 2-2 of Fig. l, Fig. 3 is view in side elevation showing the pan after the second step in the process or method ot making has' been performed, Fig. 4l top plan View showing the device ol" Fig. 3, Fig'. 5 is a bottom plan View showing the pan alter the next step in the process ot making has been performed, Fig'. 6 is a view in end elevation of the device shown in Fig. 5, Fig. 47 is a top plan View ol' the completed pan, Fig. 8 is an enlarged view in perspective showing one corner of the' completedpan, Fig. 9 is an enlarged vieuIv in perspective ot the inside of one corner of the completed pan,'and Eig. 10 is a.view taken as indicated by the line lO-iO of Fig. 8.

As shown in the drawings, .l2 indicates a blank cut from sheet metal from which the pan is 4formed. At the saine time that this blank is cut in the shape shown, a rectaiigular shaped depression as indicated by 1B is drawn, formed or pressed downwardly in the center by suitable dies. It is obvious, however, that, Without detracting from the lspirie. of this invention, the lolanls: can, he

cut in the requisiteshape and the rectangular depression .made hy separate operations. The corners et the depression 13 as indi-- cated by ilf are rounded shown to form concave-co'lrif'em'l rounded corners. The depression i3 l-'fufms the bottom of tie pan, and the rounded corners lll after heine formed by "table pressing' with properly dies, remain during,` the rest of the steps in the process or" nnikiner the pan.

Figures tl, 9 and l0, which illustrate corners of the con'lpleted par., y

Litter the lolent: has been cut and the depression i3 drawn or formed, the sides l? and ends 18 of' the pan are lient upwardly along the upper edge of the sides of said depression by any desired ineens, as with dies and press to substantially vertical positions, the corners el the blank being folded on the dottedlines shown in Fig. l, to 'form the double corners 26 Which'are permitted to project outwardly as the sides and ends are lient upwardly. lt will noted that the folds on the lines 25 do not extend to the very bottoni of the pan, but only to theopp'er edge ol the sides et the depression 13. l. have indicated the lower ends of such creases by the reference numeral 70, and it will be seen that such lower ends are considerabl,lv above the very bottom lof the pan. lt will be seen, therefore, that the rounded corners Mat the bottom of the pan do not have any creases or folds, laut are round, smooth, and seamless. After this step in the process of making, the pan is as shown in Fig. 3. y

The double or two-ply pro'ecting corner 'tlaps't are then folded against the ends ot the pan as shown in Fig, 5. i

The upper edges 29 of the pan are then lient outvvaii'dly and downwardly around a rectangular wire frame 30. in order to round and strengthen the upper edge of the pan.

It will be noted that since the creases at the corners do net go to the very bottom of the pan, they may be more tightly closed, and the adjacent layers of metal more tightly pressed together, thus doing away `with the cracks or crevices in Which.- dirt could collect. v

ilthougli, l have shown and described cer` tain embodiments et my invention it is to oe understood that it is capable of many' modifications. Changes, therefore, in the l corners clearly .shown in of dal' construction and arrangement may be made without departing` from the spirit and scope invention as disclosed in the appended claims, in which it is my intention to claim all noelty inherent in my invention as broadly as possible in view art'.

What I claim as new and desire to secure by Letters Patent. is: i

1. A pan formed from alat sheet of metal having a dmvnwardly depressed drawn bottom with rounded corners; and the sides and ends yfolded upwardly to form creases at the Corners extending only to the upper edge of the sides of the drawn bottom.

2L A pan formed from a flat sheet of materialA havingr a downwardly depressed drawn bottom with rounded corners; and sides and ends formedvabove the upper edge ol' the sides of the depressed bottom by upwardly bent material.

pan formed from a flat sheet of material having a bottom formed l:from a relatively shallow depression d -wn in the blank; and having' sides and enus above the upper edge of the sides or' said formed by upwardly bent material'.4V

4. A pan formed from a lat`sheet of material having' a bottom formed by a,

relatively shallow depression drawn in the anaterial; and sides and ends formed above the upper edge of the sides ofsaid depression by upwardly folded material.

A panv formed from a Hat sheet of material having a bottom formed by a relatively shallow depression drawn in the material; and sides an'd ends formed above of the prior depression"drawing a relatively `folding the samev at the 1,43e,eee

ing downwardly only to the upper edge the sides of said bottom forming depression.

6. The method of making a pan from a flat sheet of material comprising theforining of a bottom with rounded Corners by drawing a relatively shallow depression in the material; and forming the sides and ends of the' pan by bending the material upwardly from the upper edge of the sides of said depression-- 1 7. The method of making a `pairfrom a flat sheet of material comprising the forniing of a bottom with rounded corners by drawing a relatively shallow depression in the materia-l; formingthe sides and ends of the Jpan by bending the material upwardly from the upper edge of the sides o1 said depression and creasing the same at the corners.

8. The method of making a pan from a flat sheet of material comprising the forining of -a'bottom with rounded Corners by shallow depression in the material; bending the material outside of said depression upwardly along the upper edges of the sides of said depression to form the sides and ends of the pan7 and Corners on lines extending downwardronly to the upper edge of the sides of said depression.
